RIKEN Quantum Workshop on “Quantum-Like Modeling” in Cognitive & Social Sciences

Prospectus

Recently, there has been a growing trend to consider cognitive, and social phenomena as Open Quantum Systems, and to mathematically define the fundamental principles behind them through so-called “Quantum-Like Modeling”. It has been extremely difficult to systematically explain complexities of such phenomena within humans’ cognitive traits based on classical “rational” reasoning. Quantum-Like Modeling suggests that using quantum probability calculus and its applications could be useful to rationalize such phenomena and expand previous understandings, obtained through simple linear algebra, by applying quantum formalizations. Just as physicists explored a new branch of mathematics, the theory of operators in complex Hilbert space, to describe the quantum phenomena in an effective way, considerations here will be built on the methodology and mathematical apparatus of quantum theory and directed to applications outside of physics, namely to, cognition, psychology, decision-making, economics, finances, as well as the social and political sciences.

14:00 → 14:10 Introduction. Potential of quantum computing for humanities

The purpose and background of this workshop and the current status of this research field will be overviewed, in relation with the development of quantum computation and quantum computers and their expected potential application to the studies of humanities and social sciences in the immediate future.

Iriki is a primate cognitive neuroscientist, who had been a RIKEN Team Leader (2004~2023, BSI & BDR) and is currently a PI of RIKEN-Quantum’s Humanities section, and a Research Supervisor of JST CREST Multi-Sensing projects. He proposed an original theory of human evolution named “Triadic Niche Construction” (Phil Trans Royal Soc B, 367: 10~23, 2012), that led him to study its path integral nature.

14:10 → 15:10 Tutorial. Ubiquitous Quantum: from genetics and biological evolution to cognition, psychology, decision making, and social science

This is introduction to quantum-like modeling, applications of the methodology and formalism of quantum theory outside of physics, in cognition, psychology, decision making, social and political sciences, economics and finance, genetics and evolutionary biology. It is important to point out that systems under consideration are macroscopic. So, quantum-like theory should be sharply distinguished from It starts with the brief introduction to quantum theory (so one need not be educated in this field); the information and probabilistic counterparts will be highlighted. The motivations for quantum-like modeling will be presented and illustrated by applications to agents’ irrational behavior - disjunction and order effects. The latter in combination with another psychological effect, the response replicability effect, leads to the use of theory of quantum instruments. Quantum-like approach is used in biology, e.g., in genetics and epigenetics, for modeling adaptive dynamical interactions with environment, e.g., phenotype’s generation. Recently such models found applications in medical diagnostics of neurological diseases.

15:10 → 15:40 Quantum Instrument -- Measurement to cognition with QC-simulation

The successful modeling of compatibility of the question order effect and the response replicability effect in opinion polls opens a new research field in which quantum instrument theory unifies quantum measurement and quantum cognition with quantum computer simulation.

Ozawa has studied mathematical physics, mathematical logic, and philosophy of science. He developed quantum instrument theory and quantum set theory with contributions to foundations of quantum measurement theory, quantum information, and quantum computing, for which he received the International Quantum Award in 2010. Recently, he is extending his research interest to quantum cognition.

15:40 → 16:00 Break

16:00 → 16:30 Applications of quantum computers to cognitive sciences based on Quantum Instrument

When people are asked a series of questions, the response statistics are affected by the question-order effect and the response-replication effect. The quantum instrument model, which was originally developed as a universal mathematical model of quantum measurements, has been proposed as a model to simultaneously explain these two effects. In this study, we demonstrate the effectiveness of the quantum instrument model in cognitive science by implementing it on a quantum computer.

16:30 → 17:00 Subjective Experiences and Superposition State in Narrative Reading

In literary studies, it has been suggested that the indeterminacy of interpretation during narrative reading evokes a reader's aesthetic sense and immersion. This study modeled interpretive states with indeterminacy as a superposition using quantum probability theory, and conducted empirical research to explore how this superposition relates to subjective experiences, including transportation. This presentation will introduce and discuss part of these findings.
